Does pandas 1.3.0 support change? That's our minimum version.

Or change target to dev and let others answer #1084

@ValueRaider This seems supported, I've test with this example on pandas 1.3.0 and python 3.9.19 :

import pandas as pd
import numpy as np

date_range = pd.date_range(start='2023-01-01 00:00:00', end='2023-01-01 23:59:59', freq='S')
temperature_data = np.random.normal(loc=20, scale=5, size=len(date_range))
nan_indices = np.random.choice(len(date_range), size=100, replace=False)
temperature_data[nan_indices] = np.nan
df = pd.DataFrame({'Date': date_range, 'Temperature': temperature_data})
df.set_index('Date', inplace=True)
df['Temperature'].fillna(method='ffill', inplace=True)
minute_avg_temperature = df.resample('Min').mean()
print(minute_avg_temperature)
